A few people who have a particular disease take part in a medical trial that tests the effect of a medicine on the disease. Half

the people are given medicine and the other half are given sugar pills, which have no effect on the disease. The medicine has a 60% chance of curing someone, but people who do not get the medicine still have a 10% chance of getting well. The probability that a person gets well is ___%, and the probability that the person was cured because of the medicine is ___%.

Answer:

1.The probability that a person gets well is 70%,

2.the probability that the person was cured because of the medicine is 60%

Step-by-step explanation:

chance of curing by medicine=60%

chance of curing without medicine=10%

total chance of curing=60%+10%=70%

chance of person being cured by medicine=60%

we conclude that the store where you can get more sausages is in Peter the Butcher.

<h3>Which shop is the best option?</h3>

You have £10.

Peter the Butcher sells 6 sausages for £2.30

The number of packages that you can buy is:

£10/£2.30 = 4.3

Rounding down to the next whole number, we conclude that here you can buy 4 packages, then:

4*6 = 24 sausages

4*£2.30 = £9.20

So here you can buy 24 sausages for £9.20

In Paul the butcher, you can buy 10 sausages for £3.50

Notice that here you can only buy 2 packages (because the cost of 3 packs would be  £10.50, which is more than the amount you can spend).

Then here you only can get 20 sausages.

Then, we conclude that the store where you can get more sausages is in Peter the Butcher.

Hello what is the answer to this and the domain
nlexa [21]

We are given the following functions:

\begin{gathered} f(x)=7\sqrt[]{x}+6 \\ g(x)=x+6 \end{gathered}

We are asked to determine the composite function:

(f\circ g)(x)

The composition of functions is equivalent to:

(f\circ g)(x)=f(g(x))

Therefore, we replace the value of "x" in function "f" for the function "g", therefore, we get:

(f\circ g)(x)=f(g(x))=7\sqrt[]{x+6}+6

Since we can't simplify any further this is the composition.

Now we are asked to determine the domain of this function. Since we have a square root, the domain must be the values of "x" where the term inside the radical is greater or equal to zero, therefore, we have:

x+6\ge0

Now we solve for "x" by subtracting 6 from both sides:

x\ge-6

Therefore, the domain is:

\lbrack-6,\infty)
